Percolative effects in oxygen-depleted YBa2Cu3Ox wires
Abstract
The superconducting transition is studied in wires “written” in oxygen-depleted YBa2Cu3Ox (x∼6.4) thin films by photodoping with a near-field scanning optical microscope. The enhancement of the superconducting transition temperature observed for wide wires is found to be suppressed for wires below a sample dependent width (∼1–2μm). This behavior is understood in terms of percolation of the supercurrent through an inhomogeneous distribution of …
